Cancer??? What do you think?

I have just had a cancerous tumour removed from my gallbladder and I also have one on my liver and I am starting chemo on the 24th of this month! I recently asked a question on here which was about being worried that my boyfriend won't find me attractive with my hair loss although truthfully I know he really doesn't care, but one of the answers I received said that I was a vein ********* and should be more worried about the treatment, and although I know it shouldn't, it actually really hurt me! I have dealt with the fact I have cancer and dealt with the fact I need this treatment, that is why the question wasn't about how I felt about having the disease! Do you agree with what they said?? I really am not a vein person but it is something that concerned me, but can't help feeling hurt with the answer especially when they got a lot of thumbs up, I'm only 21 and don't think I deserved it, thanks for reading x
